Confessio Amantis ("The Lover's Confession") is a 33,000-line Middle English poem by John Gower, which uses the confession made by an ageing lover to the chaplain of Venus as a frame story for a collection of shorter narrative poems. According to its prologue, it was composed at the request of Richard II. It stands with the works of Chaucer, Langland, and the Pearl poet as one of the great works of late 14th century English literature.

In genre it is usually considered a poem of consolation, a medieval form inspired by Boethius' Consolation of Philosophy and typified by works such as Pearl. Despite this, it is more usually studied alongside other tale collections with similar structures, such as the Decameron of Boccaccio, and particularly Chaucer's Canterbury Tales, with which the Confessio has several stories in common.

The tales

The treatment given to individual stories varies widely. The Apollonius is nearly 2,000 lines long, but at the other extreme, the distinction between tale and allusion is hard to define; for example, summaries of the story of Troilus and Criseide appear in three places (II.2456–2458, IV.7597–7602, VIII.2531–2535), but none can really be described as a "tale". It follows that it is hard to produce a definite figure for the number of tales in the Confessio, since the line between allusion and tale is hard to define. Even excluding the very shortest, however, there are over 100 individual stories (Macaulay 1908), making them more numerous than the strict 100 of the Decameron, and much more so than the Canterbury Tales or the Legend of Good Women.

The best-known tales are those that have analogues in other English writers, since these are often studied for comparison. These include the Apollonius, which served as a source for the ShakespeareanPericles, and the tales shared with Chaucer, such as the tales of Constance (II.587–1603, also told by the Man of Law) and Florent (I.1407–1875, also told by the Wife of Bath).
